COBB Tuning Big SF Cold Air Intake & Airbox Subaru WRX (VA)

COBB Tuning Big SF Cold Air Intake & Airbox - Subaru WRX (VA)

COBB Tuning is one of the most respected names in Subaru performance, and the Big SF Cold Air Intake is a flagship example of why. Designed to significantly reduce pre-turbo restriction, this intake system allows the FA20DIT engine to breathe more freely — translating directly into improved airflow, greater efficiency, and real power gains when paired with proper tuning. Built from full 76mm (3 in) mandrel bent aluminium tubing and finished in satin black powder coat, it looks as good as it performs.

This listing covers the COBB Big SF Cold Air Intake and Airbox kit for the Subaru WRX VA chassis, covering model years 2015 to 2021.

Important: Proper ECU tuning is mandatory with this intake. You must use COBB's associated +BigSF Off-The-Shelf (OTS) maps, or have your vehicle tuned by a COBB Certified Protuner. Running this intake without a tune may result in poor drivability or engine damage.
